Galaxy evolution since cosmic noon: lessons from gas, dust and star formation |
Seminar Title | Galaxy evolution since cosmic noon: lessons from gas, dust and star formation | | | Speaker: | Dr. Stijn Wuyts | | | Affiliation: | (University of Bath) | | | When | Thursday morning, Aug.30, 10:30 a.m. | | | Where: | Room 302, No.3 building , Xianlin campus (PMO, CAS) | | Welcome to Attend | | | ( PMO Academic Committee & Academic Circulating committee) | | Abstract: Integral-field spectroscopic surveys such as MaNGA in the nearby Universe and KMOS3D out to z~2.6 are providing us with a 3D mapping of the ionized gas emission in large samples of mass-selected star-forming galaxies. Their dynamics reveal the depth of gravitational potentials in which the gas orbits. Broad components to the line emission shed light on galactic-scale outflows driven by star formation and active nuclei. Moreover, the spatial distribution of ionized gas emission serves as a tracer of where within galaxies the (unobscured) star formation is taking place. Complementing these rest-optical observations are far-infrared measures of dust and CO line emission, probing the cold gas reservoirs, molecular outflows and the distribution of dust-obscured star formation. I will present recent findings on the nature and evolution of star-forming galaxies from cosmic noon to the present day, obtained by combining multi-wavelength tracers of dust and star formation, ionised and molecular gas. |
